A septuagenarian couple leaving for Los Angeles in California, USA was held at the Ninoy Aquino International Airport (NAIA) terminal 1 after a live bullet for a .38 caliber gun was found in their carry-on bag on Tuesday afternoon. Esteban Cortabista, 78, and his wife Salvacion, 75, both passengers of Korean Air flight, were prevented to the boarding lounge after Office for Transportation Security (OTS) personnel stopped them at the final security check. The couple denied owning the bullet saying it was their second time to travel to the US and knew that carrying bullet in the airport terminal is prohibited. The couple was later brought to the medical clinic after Salvacion complained of difficulty in breathing as her blood pressure shoot-up. Police Aviation Security Group said that the couple was brought to the Department of Justice for further investigation.
